SPECIFICATION forming part of Letters Patent No. 788,643, dated May 2, 1905.

Application iled March 2, 1904. Serial No. 196,127.

To (all whom, t muy Concern:

Be it known that 1, ROBERT H. HARTLEY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Oon-Oontrolled Exerciser, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawing, in which the figure is a perspective view, partly broken away, showing my improved exerciser.

My invention relates to the class of exercisers, and is designed to provide a device of this character which shall be normally locked and can be unlocked by the insertion of a coin and the exerciser then used for a certain period of time, after which it is again automatically locked.

ln the drawing the cords 2 2 lead to exter- 4 nal handles, which are used in the ordinary manner of an exerciser. The cords 2 2 extend through upper holes in the cabinet 3 and form the end portions of the common cord 4 within the cabinet. pulley 5, the end portions extending over the pulleys 6 6 and out through the holes. The pulley 5 is connected to a cord 7, which is wound around the lower pivoted drum 8 and thence extends upwardly and around a top pulley 9 and thence down to a strong spring' 10, to which its other end is connected.

When the handles are pulled outwardly, the pulley 5 is lifted, the drum turned in a counterclockwise direction,` and the spring 10 elongated, this spring aording a resistance to the pull. When the operator allows the handles to move back, the drum rolls in a clockwise direction under the tension of the spring 10. The rim ll of the drum is provided with a lug or pawl 12, which engages the teeth of a ratchet-wheel 13, the teeth of which are also engaged by the spring-pressed dog 14. The Wheel13 carries a laterally-projecting pin 15, which is adapted to engage the lower edge of a lever 16, pivoted in the case at 17 and having at its rear end a lug 18, arranged to engage a pin 19 on the coin-receiving lever 20. The forward end of the lever 17 is connected to a light spring 21, which normally holds the lug 18 in lifted position, allowing the stop 22 on the coin-lever to drop down into the path This cord 4 extends over a lower of a pin 23 on the rear rim of the drum. The stop portion 22 of the pivoted lever 2O is heavier than the other coin-receiving portion 24. thereof.

When a coin is dropped in through the slot 25, it slides down through the chute 26 and drops into the receiving-slot of the lever 20, being held at this time by a fixed lug 27 on the inside of the ease. The weight of the coin tilts the coin-lever and lifts the stop 22 out of the path of the pin 23, thus unlocking the apparatus. The machine will then be used, and during its use the oscillations of the drum gradually turn the ratchet-wheel in one direction, and the pin 15 travels over beneath the lever 16 and lifts it against the tension of the spring 21. This causes the lug 24 to depress the coinereceiving portion of the coin-lever until the coin drops down into the cabinet or a receptacle therein. The pin 15 is then gradually lowered in passing over to the opposite side, and this allows the spring 21 to lift the lug 24, so that the stop 22 will drop into the path of the pin 23, thus relocking the apparatus. The apparatus cannot then be used until another coin is dropped into the slot to lift the stop and unlock the device.

VThe advantages of my invention result from providing a coin-controlled lock which allows the use of the exerciser in connection with mechanism which automatically relocks the device after a short period of use.

Many variations may be made in the form and arrangement of the exereiser, the lock and coin release, and other parts without departing from my invention.

1. An exercising-machine having external pulling devices, a yielding resistance therefor, a lock, a coin-controlled release for the lock and mechanism actuated by the exereiser and arranged to relock the same after a predetermined number of movements of the pulling devices; substantially as described.

2. An exereiser having external cords, a yielding' resistance for the cords, a drum arranged to be turned by pulling the cords, a lock to prevent turning of the drum, a coincontrolled release for the lock, and mechanism reset the lock after a predetermined number IO of movements; substantially as described.

In testimony whereof I have hereunto set my hand.
